Quickfix SessionID Conflict

The opensource quickfix library uses BeginString-TargetCompID-SenderCompID as sessions map's key. cTrader FIX API credentials uses the same ID resulted conflicts when connecting to trade & quote simultaneously. Although the TargetSubID is different, it's not used by quickfix as mapping key.

Would it be possible to change the current TargetCompID to something else? i.e cServer-Trade and cServer-Quote for the two sessions.

thanks
